A new study by Tulane University researchers, published in the March edition of Molecular Endocrinology, provides insight into one of the ways diethylstilbesterol (DES) may alter the development of the uterus.
DES, a synthetic estrogen, was prescribed to prevent miscarriage in many women who were pregnant between 1941 until 1971. In 1971, DES was banned in the United States due to concerns about the occurrence of cancer and infertility in the daughters of women who took it.
“Several millions of pregnant women were treated with DES and we have continued to study and model the disease since it provides unique insights into what estrogenic chemicals may do to the developing fetus,” says study co-author John McLachlan, director of the Center for Bioenvironmental Research at Tulane and Xavier Universities. “There are other chemicals in our environment -- the results of industrial, agriculture and chemical processing -- that, while their estrogenic affect is weaker, may affect developing embryos in the same way. We need models to understand the cellular and genetic mechanisms by which environmental chemicals work. This study is a step in that direction.”

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
